Grafana v6.7 introduces several new features and improvements, including enhancements to authorization, enterprise reporting, and a new plugin for Google Sheets. Key updates include Azure OAuth integration for assigning users and groups to Grafana roles via Azure Active Directory, a minimum refresh interval for dashboards to reduce load on data sources, and a project selector for querying different projects within Google Cloud Platform's Stackdriver without changing the datasource. The release also brings Enterprise features such as customizable application titles through white labeling, configurable reporting for timeout and concurrency, and the capability to export dashboards as PDFs in either portrait or landscape mode. Additionally, there is Azure OAuth Team Sync support and a beta version of query history, allowing users to interact with and manage previous queries directly from their browser.
